Charging circuit, charging method, and terminal

A charging method applied in a terminal, wherein the terminal comprises a charging circuit, the charging circuit comprises a charging interface, a control circuit, a connector, and a battery electrically connected in sequence;

• the battery is configured to be connected with a motherboard of a terminal to supply electric power to the terminal;
• the charging interface is configured to receive a charging current and a charging voltage;
• the control circuit is configured to control a pathway between the charging interface and the connector, so as to transfer the charging current and the charging voltage to the battery via the connector, and thereby charge the battery;
• wherein the charging method comprises:
• receiving the charging current and the charging voltage by the charging interface;
• controlling, by the control circuit, the pathway between the charging interface and the connector;
• and
• transferring, by the connector, the charging current and the charging voltage input from the charging interface to the battery to charge the battery;
• wherein the battery is a serial dual battery, the connector comprises a charging connector and a discharging connector, the serial dual battery is integrated in a battery protection plate;
• and the method further comprises:
• electrically connecting, by the control circuit, the charging interface with the charging connector;
• electrically connecting the charging connector with the battery protection plate;
• and electrically connecting, by the discharging connector, the battery protection plate with the motherboard of the terminal.
